I dont get it, i leave the car sit for 10 days to go on vacation, and i come back and the new fuel pump i installed just prior to vacation has no response i dont hear it priming up. What would cause this ? The car ran just fine before i left, now it just cranks but no start......

I ran diag and got a code 54, i checked the fuse underneath and it was fine, are there any other fuses related to the pump. i dont want to drop the tank again.......

Okay i replaced the fuel pump relay and still no fire, i cant believe that a fuel pump would go bad after only a week, anything else i could try ?
